Uivrrnn STATES PATENT WINDMiLL.

SPECIFICATION forming part of Letters Patent No. 317,731, dated May 12,18815.

Application led February 28, 1885.

.To @ZZ whom if may concern.'

Be it known that we, HUTsoN B. GoLMAN and GEORGE TURNER, citizens of theUnited States, residing at Kalamazoo, county of Kalamazoo, State ofMichigan, have jointly invented a new and useful Power-Windmill, ofwhich the following is a specification.

This invention has for its object improved means of transmitting powerfrom a windplace.

wheel shaft having a swiveled bearing-support to a shaf't or machineryhaving a stationary bearing-support.

In the accompanying drawings, forming a part of this specification,Figure 1 is a side elevation, portions of which are in vertical section5 Fig. 2, an under plan view of parts in Fig. l, referred to by likeletters g and Fig. 3, a top plan of a part in Fig. 1, also referred toby like letters, all of which are fully described below. f

Referring to the letters marked on the drawings, P is the wind-wheelshaft, B the swiveled bearing-support of said shaft, and r r areconcentric tubular power-shafts passing through the tubular pendentportion of the swiveled bearing-support, free to rotate'independently ofthe movement of said support and windwheel in turning from one pointofthe compass to another, suspended from said support, and gear connectingwith the wind-wheel shaft each side of the vertical center of thebearingsupport B in a manner to be rotated in opposing directionsindependently of each other. The gears a c form shoulders or heads tothe shafts, preventing them from falling out of The gear c of the shaftr meshes with the gear c at the wheel-shaft P, and the gear c' of thelatter-named shaft meshes with the gear a of the power-shaft i", all inthe manner of heretofore constructing and gearing these parts. Theshafts have suitable guide-sup ports in the fixed beam It. To thesesuspended shafts r r we connect gears, as in Figs. land 2. The largergear, A, is provided with internal cogs, and is secured to the shaft i,and the smaller gear within the larger is secured to the shaft 1^. Thisgear D is provided with a cogged periphery. These gears turn in opposingdirections, one within the other, when the shafts i i" rotate.

The gear E of a vertical shaft, c', meshes with the gears A D, andtraverses the space (No model.)

between the latter gears around the powershafts r fr. An arm, a, isswiveled at s to one of the powershafts, and has bearings in its outerend for the shaft e. The lower end of the shaft c has bearings in thegroove of the rim R, around which groove said lower end' support, itmatters not at what point ofthe coin-V pass the wind-wheel may berunning, and this rotary motion is kept up during the shifting of thewheel, for the reason that when the wheel shifts the gears A D areturned withit, carrying the shaft c and its gears E f in a circle aroundthe power-shafts, or part way around, as the case may be, owing to thedistance the wheel shifts at a given time, thus causing the gears A D Ef s to be at all times in operative relation. In this operation thegears A D eX- ert each an equal leverage on the gearE, they beingproperly proportioned and cogged to this end; and the resistance of thework being done by the shaft r, or machinery connected with it, does notcant the wheel out of its proper position in the wind. Of coarse, theaxial center of the shaft fr is in vertical line with the verticalcenter of the bearing-support B, said center being at the pointindicated in the drawings by the chain passing vertically through themill. The gears a o and shaft of the latter show how motion may befurther transmitted to a horizontal shaft having a fixedbearing-support, which support in the drawings is the stationary beam t.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is- Y The combination of a windwheel shaft, aswiveled bearing-support therefor, concentric power-shafts suspendedfrom the bearing-support and forming operative engagement with thewheel-shaft on opposite sides of the vertical center of saidbearing-support, and adapted to independently rotate in opposingdirections, a gear connecting with and suspended by each power-shaft, ageared shaft having a statioir IOC ary bearing-support,v and a movableshaft unto subscribed your names in presence of two provided with gearsforming engagement Witnesses. with said geeredshaft and with the gearsof I HUTSON B GOLMAN. the owenshaft-s sind movable shaft havlngbearlsngs allowing it to traverse eeirele around GEORGE TUhNERthevertieal center of the power-shafts, all sub- Witnesses stentielly asset forth.
